Article: "Spinning the Threads of Quantum Memory"

August 26, 2021

A study at the Weizmann Institute of Science has proposed a new method to store information in qubits for longer periods of time. While regular computers store data using “bits” that can exist as either a 1 or a 0, quantum computers can maintain both states at the same time, a phenomenon known as superposition. This quality gives quantum computers the potential to process data at a much greater speed and scope than existing technologies. However, a qubit is very sensitive to its physical environment, which can result in its data to be lost in just a tiny fraction of a second.

While quantum computers have stored data through the two different spins on electrons (clockwise or counterclockwise), the new method capitalizes on the spin direction of alkaline gas, which is transferred to the nuclei of rare noble gases through collision, which can hold its spin direction for several months, an improvement over the tenths of a second information can currently be stored for in qubits. While much more research is needed, the potential exists to finally create a stable quantum memory system, opening the floodgates of the true power of quantum computing.
